Monel puas tuaj yeem welded?
Arc vuam cov txheej txheem ntawm monel alloys
Raws li ib qho alloy ua feem ntau ntawm cov hlau tsis yog, oxyacetylene thiab lwm yam kev siv roj roj roj roj tsis siv rau Monel. Cov kab tsib xee npe yog yuav sib khi nrog cov pa roj atmosphen thiab hydrogen tsis muaj ntawm qee yam ntawm cov ntaub thaiv npog roj lossis flux, tsim cov qog thiab suav. Koom nrog cov Monel yog qhov zoo tshaj plaws ua tiav los ntawm hluav taws xob vuam. Txhua hom kev vuam arc muab txoj kev pov thaiv cov hlau thaiv molten thiab tiv thaiv cov weld los ntawm kev ua paug. Thaum txhua hom kev sib tw arc tuaj yeem siv tau rau Monel alloys, qee cov vuam cov txheej txheem tau paub ua haujlwm zoo dua li lwm tus.
Vuam Monel Nrog SMAW
Cov thaiv hlau arc vuam (smaw) lossis lo vuam yog los ntawm kev sib tw ntau tshaj plaws. Monel tuaj yeem welded nrog smawe siv cov npe loj ntawm ob npib hluav taws xob thiab ncaj qha tam sim no. Txawm li cas los xij, tsim kom muaj qhov sab hauv sab hauv sab hauv rau cov weld yuav tsum tau siv lub hnab thaub qab txij li smawb thaiv ntawm cov hlau sab hauv ntawm cov hlau molten. Monel kuj tseem muaj yooj yim rau kev tawg vim muaj cua sov, thiab smaw vuam cov tswv yim ntau dua li cov roj av ntawm arc vuam. Kev thauv yog qhov tshwj xeeb tshaj yog cov qhib-zawj vuam uas yuav tsum tau ntau cov kev hla uas siv cov qauv wave los sau cov sib koom tes. Monel tseem yuav ua paug yog tias pas dej weld yog nthuav tawm rau cov huab cua, thiab tsis muaj kev tiv thaiv kev tiv thaiv, paug yog qhov nyuaj rau kev zam. Cov nqi tso nyiaj nrog cov txheej txheem smaw ntawm Monel kuj tsis zoo tagnrho.
Vuam Monel nrog Cov Roj Tiv Thaiv Roj Vuam Arc Vuam Vuam
Cov kev thaiv cov roj thaiv cov hau kev ntawm arc vuam muaj ntau tus yam ntxwv uas ua rau lawv nyiam rau siv nrog Monel. Cov kev pab roj yog qhov tseem ceeb thaum vuam moel. Zoo ib yam li kev oxygen kis tau tuaj yeem ua rau paug rau thaum vuam titanium thiab txhuas, necert alloys tuaj yeem ua rau porosity heev. Inert cov tshuaj tiv thaiv roj zoo li Argon muab ib qho nruab nrab uas tiv thaiv cov cua ib puag ncig los ntawm kev hu rau Molten Monel. Cov roj tuaj yeem tso tau rau hauv sab hauv ntawm cov yeeb nkab lossis lub nkoj siab, thiab cov weld tuaj yeem tiv thaiv los ntawm ob sab. Lub peev xwm no yuav tiv thaiv los ntawm ob sab ua kom zoo dua rau cov pa hluav taws xob hauv Weld saum thiab cov pa roj oxygen, lossis cov pa roj oxygen, lossis cov pa roj oxygen, lossis cov pa roj oxyen, lossis cov pa roj oxyen, lossis carbon kom paug cov weld ntev npaum li tau npaj ua ntej. Cov khoom thaiv cov roj thaiv cov roj arc vuam kuj tseem tso cai rau kev tswj hwm cov lus qhia tshav kub rau hauv cov hlau. Qhov kub ntawm cov txheej txheem vuam tuaj yeem hloov pauv los ntawm kev siv sib xyaw ntawm argon thiab helium, lossis hydrogen zoo li. Cov roj av nrawm nroos ntws ntawm cov ntaub thaiv cov roj sab hauv thiab tawm kuj txhim kho weld nkag, txo qhov peev xwm rau cov crevices thiab nqaws hauv Weld. Ntawm ob hom roj thaiv cov roj thaiv arc vuam cov txheej txheem, gtaw yog qhov zoo tshaj ob txoj hauv kev rau theem ntawm kev tswj hwm nws muaj.
